Abstract
Disclosed are methods for preparing a thin film composite membrane by subjecting a solution comprising one or more zwitterionic copolymers to an electrospraying process, thereby preparing the thin film composite membrane.
Claims30
A method of preparing a thin film composite membrane, comprising the steps of:
- i) preparing a solution comprising one or more zwitterionic amphiphilic copolymers, wherein each of the zwitterionic amphiphilic copolymers comprises a plurality of hydrophobic repeat units and a plurality of zwitterionic repeat units;
- ii) subjecting the solution to an electrospraying process using an electrospray device;
- and
- iii) depositing the zwitterionic amphiphilic copolymers onto a porous substrate to form a selective layer;
- thereby producing the thin film composite membrane.
